Hereinafter, embodiments of the present invention will be described with reference to the drawings.

First Embodiment

FIG. 1 is an overall view of a field management system 1 according to the first embodiment. The field management system 1 is a system for monitoring the field 3. For example, in the field management system 1, a communication device 10 having a physical quantity detection part 11 is installed in a field 3, and when a physical abnormality such as intrusion into the field 3 is detected by the physical quantity detection part 11, management of multicopter etc. When the machine 30 reaches the field 3, abnormality can be confirmed.

As shown in FIG. 1, the field management system 1 includes a plurality of communication devices 10 and a dispatching part 20. A plurality of communication apparatuses 10 are installed in the field 3. For example, in the field 3, a plurality of fruit trees 4 are planted, and the communication device 10 is installed in each of the fruit trees 4 to be monitored. The communication device 10 may be embedded in the entrance and exit of the field 3, on a different ground or wall from the monitored object, or may be disguised as the fruit 41 (as the fake fruit 4 a).

In such a case, the communication device 10 may be installed separately from the camouflaged fruit 4 a and the camouflaged fruit 4 a, or only one of them may be installed. The communication device 10 is operated by a power source such as a dry cell battery, a button battery, a solar cell, a secondary battery or the like built in the communication device 10. The communication device 10 may be operated by an external power source.

The dispatching part 20 is capable of communicating with the plurality of communication devices 10 and the management device 30, and is a device that performs processing relating to the dispatch of the management device 30. In this embodiment, the dispatching part 20 is a device that performs processing relating to dispatch of the management machine 30, but may be a relay device that relays communication between the communication device 10 and the management device 30, or may be a communication device 10 and the server 50, or may be a relay device that relays communication between the mobile terminal 60 or the like and another device.

Next, the communication device 10 will be described in detail.

The communication device 10 includes a physical quantity detection part 11, a first communication part 12 and a determination updating part 13. The physical quantity detection part 11 includes an acceleration sensor, a strain gauge, a light sensor, a magnetic sensor and the like, and is a device capable of detecting dynamic movement of people, animals, objects, and the like. The communication device 10 has one or more physical quantity sensors as described above.

Under the second condition and the third condition, the third condition is a condition with a high degree of urgency. The third condition is a condition having a particularly high degree of urgency, for example, a condition for notifying the server 50 etc. immediately before the communication device 10 is taken away or destroyed.

The fourth condition is a condition for notifying failure of the communication device 10, necessity of power supply replacement, or the like. In the present embodiment, the notification determination condition is four conditions from the first condition to the fourth condition, but may be three or less, or five or more conditions.

Further, when the communication apparatus 10 includes a plurality of physical quantity detection parts 11, the notification determination condition may be a condition based on a combination of physical quantities detected by the plurality of physical quantity detection parts 11. Also, conditions based on conditions such as elapsed time may be used.

The judgment updating part 13 updates the notification judgment condition when there is an instruction (update instruction) for updating the notification judgment condition from the dispatching part 20 or the management machine 30. In the present embodiment, the values of the predetermined thresholds F1, F2, F3 are changed. It should be noted that the update of the notification determination condition may be performed by adding not only the notification determination condition previously registered but also a new notification determination condition.

The mobile terminal 60 is a relatively high calculation capability. The mobile terminal 60 includes a fifth communication part 61, a display part 62, and a position detection part (position detection device) 63.

The fifth communication part 61 is a device that performs wireless communication with the dispatching part 20 and the server 50. The fifth communication part 61 performs wireless communication with the dispatching part 20 and the server 50, for example, by Wi-Fi or the like. The fifth communication part 61 may perform wireless communication with the dispatching part 20 or the server 50 via a data communication network, a cellular phone communication network, or the like. The fifth communication device 61 transmits to the dispatching part 20 and the server 50 a signal (activation information) for causing the communication device 10 to return from a stealth mode to be described later.

The display part 62 can display a screen as shown in FIGS. 14 to 19. It is possible to display the monitoring screen Q2 or the like based on the home screen Q1 or the field information received from the server 50 by the fifth communication part 61. That is, the detection information and the information of the field 3 can be displayed.

The position detection part 63 is a device that detects its own position (positioning information) by the satellite positioning system. The position detection part 63 receives a signal transmitted from the positioning satellite G, and detects its own position (for example, latitude and longitude) based on the received signal. That is, an operator who works in the field possesses the portable terminal 60 at the time of work, thereby detecting the position of the worker at the time of work.

The field management system 1 has a communication device installation location registration mode (mapping mode), a monitoring mode (abnormality detection mode), and a determination condition update mode.

Hereinafter, the mapping mode, the monitoring mode, and the determination condition update mode will be described in detail.

The mapping mode is a mode in which the installation location of the communication device 10 installed in the field 3 is measured and the positioning information is registered in the server 50. A switching instruction (field registration instruction) from the mobile terminal 60 to the mapping mode is performed by operating the portable terminal 60. Specifically, as shown in FIG. 14, the creation button 102 provided on the home screen Q1 is selected (tapped).

When the monitoring button 103 is selected, as shown in FIG. 20, the screen display of the display part 62 transitions to display a monitoring state screen Q2 as shown in FIG. 16A. The field map 201 is displayed on the upper part of the monitoring situation screen Q2. On the field map 201, a map around the field is displayed based on the field information stored in the storage part 52 of the server 50. For example, “Field A”, “Field B”, “Field C”, and “Field D” are displayed in FIG. 16A.

When any one of the fields 3 displayed on the field map 201 is selected, as shown in FIG. 20, the screen display of the display part 62 transitions and the monitoring situation screen Q3 of each field is displayed. When the creation button 308 arranged at the bottom of the monitoring situation screen Q3 of each field as shown in FIG. 16B is selected, a field registration instruction is transmitted from the mobile terminal 60 to the server 50.

As shown in FIG. 10, when the server 50 determines that a field registration instruction has been received from the mobile terminal 60, the registration instruction part 51 b 2 instructs the management machine 30 to switch to the mapping mode. As shown in FIG. 20, when the switching instruction to the mapping mode is completed, the display part 62 of the portable terminal 60 displays the home screen Q1.

When determining that the switching instruction to switch to the mapping mode is received from the server 50, the management machine 30 checks whether field information is stored in the management storage part 46. When the field information is not stored in the management storage part 46, the management machine 30 requests the server 50 to transmit the field information. In response to a request from the management machine 30, the server 50 transmits the field information stored in the storage part 52 of the server 50.

The management machine 30 moves to the field 3 based on the acquired field information or the field information stored in advance in the management storage part 46 and the positioning information detected by the position detection part 41. As shown in FIG. 2B, the management machine 30 moves within the field 3 after moving to the field 3. The management device starts detecting the identification information outputted by the communication device 10.

After starting, the communication device 10 initializes the transmission power of the output part 12 and outputs the identification information 1). Further, the communication device 10 initializes the notification determination condition. The physical quantity detection part starts detecting the physical quantity.

When acquiring the identification information outputted by the communication device 10, the management device 30 determines whether there is a communication device that outputs unregistered identification information based on the acquired field information or the field information stored in the management storage part 46 to decide.

The management device 30 requests connection to the communication device 10 that outputs unregistered identification information. The communication device 10, which is requested to be connected to the management device 30, performs communication connection according to a request from the management device 30.

The management device 30 communicates with the communication device 10 via the management output part 42 b and the management receiving part 12 a and switches the communication device 10 to the mapping mode. When switching to the mapping mode via the management receiving part 12 a, the output part 12 b of the communication device 10 temporarily reduces the output.

After disconnection of the communication with the communication device 10, the signal receiving part 42 a of the management device 30 receives the identification information outputted by the output part 12 b of the communication device 10 that has switched to the mapping mode. The first acquiring part 43 of the management machine 30 acquires the identification information received by the signal receiving part 42 a.

The management machine 30 checks whether the radio wave reception strength of the identification information acquired by the first acquisition part 43 is equal to or larger than a predetermined threshold value based on the threshold value stored in advance in the management storage part 46.

In the determination of a point where the radio wave reception intensity (radio wave intensity) is equal to or greater than the predetermined threshold value, the field 3 is divided into lattice (mesh) shapes, and radio field intensity of each communication device 10 is compared for each mesh 3 a. Specifically, as shown in FIG. 9, the management machine 30 acquires the field information acquired from the storage part 52 of the server 50 via the server output part 51 b and the signal receiving part 42 a, or the field information stored in the management storage part 46 Based on the field information, move in the field 3.

Compares the reception strength of the identification information of each communication device 10 received by the signal reception part 42 a, and estimates the position of the communication device 10. For example, the numerical value in each mesh 3 a shown in FIG. 3D indicates the radio field intensity of the communication device 10 arranged at the point B-3 in each mesh 3 a. In this case, it is estimated that the communication device 10 is installed at the point B-3 where the radio wave intensity received by the management device 30 shows the local maximum value.

As shown in FIG. 3A, when the manager 30 is in the mapping mode, the position detecting part 41 detects a position at a point where the radio field strength acquired by the first acquiring part 43 is equal to or larger than a predetermined threshold value. The second obtaining part 44 obtains the positioning information detected by the position detecting part 41.

The associating part 45 associates positioning information at a point where the radio wave intensity acquired by the first acquiring part 43 is equal to or larger than a predetermined threshold with the updated identification information. The association information (positioning information, identification information) is stored in the management storage part 46.

Or it is temporarily stored in the management storage part 46 and transmitted to the server 50 via the management output part 42 b and the fourth acquisition part 51 a. The registration part 53 of the server 50 registers the association information and the field information such as the field name and the field position in the storage part 52 in association with each other.

The management machine 30 requests the communication device 10 for which registration of the field information has been completed via the management output part 42 b and the receiving part 12 a to update the identification information. The communication apparatus 10 updates the identification information in response to a request from the management machine 30.

After disconnecting communication with the communication device 10, the management device 30 starts detecting the output of the other communication device 10. Based on the updated identification information stored in the management storage part 46 or the storage part 52, the management machine 30 determines whether or not the position information has been registered.

That is, as shown in FIG. 3B, in the mapping mode, the manager 30 does not request connection to the communication device 10 that outputs the updated identification information. In other words, the management device 30 requests connection only to the communication device 10 that outputs the identification information before updating. When there is no communication device 10 that outputs the identification information before updating, the management device 30 terminates the mapping mode.

In the present embodiment, the output part 12 b outputs the identification information and the notification information as radio waves, but may output such as light. For example, the output part 12 b outputs the light emission pattern indicating the identification information of the plurality of communication devices 10.

As shown in FIG. 3C, the position detection part 41 detects positioning information at a point where the reciprocal of the horizontal distance between the light acquired by the first acquisition part 43 and the first acquisition part 43 is equal to or larger than a predetermined threshold value.

The associating part 45 associates the positioning information at the point where the reciprocal of the horizontal distance between the light acquired by the first acquiring part 43 and the first acquiring part 43 is equal to or larger than a predetermined threshold and the updated identification information. The association information is stored in the management storage part 46.

Or it is temporarily stored in the management storage part 46 and transmitted to the server 50 via the management output part 42 b and the fourth acquisition part 51 a. The registration part 53 of the server 50 registers association information and field information in the storage part 52 in association with each other.

Next, the monitoring mode will be described. The monitoring mode detects a dynamic abnormality such as invasion of a person invading the field 3 or an intruding animal. The mode is a mode in which the management machine 30 is dispatched to the detection part of the abnormality based on the position information. The switching instruction to the monitoring mode is performed from the portable terminal 60 or the like connected to the server 50.

More specifically, for example, as shown in FIG. 14, the monitoring button 103 on the home screen Q1 of the mobile terminal 60 or the like is selected. When the monitoring button 103 is selected, as shown in FIG. 16C, a monitoring status screen Q2 is displayed.

When the monitoring button 204 on the monitoring situation screen Q2 is selected, the portable terminal 60 instructs the server 50 to switch to the monitoring mode. (Monitoring instruction) to the monitoring mode from the monitoring instructing part 51 b 3 of the server 50 via the signal receiving part 42 a and the server output part 51 b.

Upon receiving the monitoring instruction, the management machine 30 stands by at a predetermined standby location 3 b such as the vicinity of the field 3 shown in FIG. 2A. When the switching instruction to the monitoring mode is completed, as shown in FIG. 20, the screen display of the display part 62 transitions to the home screen Q1.

The communication device 10 initializes the output of the output part 12 b and initializes the determination condition. The physical quantity detection part 11 starts detecting the physical quantity. The notification creation part 12 c determines whether or not the physical quantity detected by the physical quantity detection part 11 matches any one of the notification determination conditions.

When the first condition (semi-dangerous) of the notification determination condition is met, the notification creation part 12 c creates first notification information indicating that it is semi-dangerous. The output part 12 b of the communication device 10 outputs the first notification information created by the notification creating part 12 c.

When the second condition (danger) of the notification determination condition is met, the notification creation part 12 c creates second notification information indicating danger.

When it matches the second condition (danger) of the notification determination condition and does not match the third condition (urgent), the output of the output part 12 b is initialized.

The output part 12 b of the communication device 10 outputs the second notification information created by the notification creation part 12 c.

When the third condition (urgent) of the notification determination condition is met, the notification creation part 12 c creates third notification information indicating that it is urgent.

The communication device 10 checks whether there is a connection request from the dispatching part 20. When there is no connection request from the dispatching part 20, the output part 12 b of the communication device 10 sets the output of the third notification information created by the notification creating part 12 c, and does not output the third notification information. A state in which the output part 12 b sets the output of the third notification information and does not output the third notification information is also referred to as a “stealth mode”.

When the fourth condition (ERROR) of the notification determination condition is met, the notification creation part 12 c creates fourth notification information indicating that ERROR has occurred. The output part 12 b of the communication device 10 outputs the fourth notification information created by the notification creation part 12 c.

When any of the notification determination conditions is not satisfied, the output part 12 b of the communication device 10 sets the identification information. The output part 12 b outputs the identification information.

The output part 12 b of the communication device 10 outputs the first notification information, the second notification information, and the fourth notification information generated by the notification creating part 12 c with different radio wave outputs. More specifically, the first notification information and the fourth notification information are output with smaller radio wave output than the second notification information.

The second communication part 21 of the dispatching part 20 detects notification information of the communication device 10. The call determination part 21 c determines whether notification information is output.

When the call determination part 21 c determines that the notification information is not output from any of the plurality of communication devices 10, the signal reception part 42 a receives the activation information from the server 50 or the mobile terminal 60 And confirms whether or not it is done.

When the signal receiving part 42 a receives activation information from the server 50 or the mobile terminal 60, the dispatching part 20 starts detection of the communication device 10 not outputting the notification information. The dispatching part 20 makes a connection request to the detected communication device 10.

The communication device 10 that meets the third condition makes a connection according to the connection request. The second communication part 21 of the dispatching part 20 requests the communication device 10 to increase the output of the output part 12 b.

If there is a request to increase the output of the output part 12 b, the communication device 10 increases the output of the output part 12 b and outputs the third notification information from the output part 12 b. The second communication part 21 disconnects the communication after requesting an increase in the output. After checking the request to increase the output of the output part 12 b, the communication device disconnects the communication.

If the communication device 10 determines that there is no request to increase the output from the second communication part 21, the communication device 10 disconnects the communication.

When notification information is not output from any of the plurality of communication devices 10 and no activation information is also acquired, the call determination part 21 c determines not to call the management device 30.

When the call determination part 21 c determines that notification information is output from any of the plurality of communication devices 10 from the output part 12 b, the third acquisition part 21 a of the dispatching part 20 acquires the notification information.

When the third acquisition part 21 a determines that the third notification information has been acquired, the call determination part 21 c determines, on the basis of the third notification information acquired by the third acquisition part 21 a, the calling number 3 Create call information.

If the notification information acquired by the third acquisition part 21 a is not the third notification information, the call determination part 21 c confirms whether the notification information acquired by the third acquisition part 21 a is the first notification information.

If the notification information acquired by the third acquisition part 21 a is the first notification information, it is detected whether there is notification information of another communication device 10. The call determination part 21 c checks whether or not the other communication device 10 is outputting the second notification information.

If it is determined that the second notification information is not output, the call determination part 21 c creates the first call information based on the first notification information. In other words, when the notification information acquired by the third acquisition part 21 a is only the first notification information, the call determination part 21 c creates first call information to be called due to occurrence of semi-danger on the basis of the first notification information.

On the other hand, when the third acquisition part 21 a detects the first notification information and detects the second notification information outputted by the other communication device 10, the call determination part 21 c determines, on the basis of the second notification information having a high degree of danger Create second call information to call due to occurrence of danger.

Further, when the notification information acquired by the third acquisition part 21 a is not the first notification information and the third notification information, the call determination part 21 c confirms whether the notification information is the second notification information. When the notification information is the second notification information, the call determination part 21 c creates the second call information based on the second notification information.

When the notification information acquired by the third acquisition part 21 a does not correspond to any of the first notification information, the second notification information, and the third notification information, and in the case where the fourth notification information is acquired, the fourth notification information The management output part 42 b transmits the notification information to the server 50.

Hereinafter, the management machine 30 responding to the call of the dispatching part 20 will be described.

In a case where neither the mapping mode nor the determination condition update mode is applicable, the management machine 30 detects whether the first call information, the second call information, and the third call information are output. The management machine 30 that acquired the call information via the signal receiving part 42 a transmits the call information to the server 50. The management machine 30 requests the server 50 to transmit the positioning information of the communication device 10 that output the notification information.

When the fourth acquisition part 51 a acquires the call information, the server 50 responds to the connection request of the management machine 30. Based on the call information acquired by the fourth acquisition part 51 a, the association information stored in the storage part 52, and the field information, the server 50 identifies the positioning information of the communication device 10 that output the notification information. The server output part 51 b outputs the positioning information to the management machine 30.

The signal receiving part 42 a receives the positioning information, and the management machine 30 moves to the installation location of the communication device 10 that output the notification information based on the positioning information. In this manner, the management machine 30 is called up at the installation location of at least one communication device 10 among the plurality of communication devices 10 that output the notification information.

After moving to the installation location of the communication device 10, the management device 30 performs predetermined actions based on the call information. For example, the management machine 30 performs a warning action by the warning part 48 and/or a monitoring action by the monitoring part 47.

More specifically, as shown in FIG. 2A, the warning part 48 issues a warning sound to warn the intruder M2. When the monitoring part 47 is a video camera that captures moving images, it captures moving images around the communication device 10 as a movement destination. The captured moving image data is associated with the identification information and stored in the management storage part 46.

After moving to the predetermined standby location 3 b, the management machine 30 transmits the information associating the moving image data and the identification information to the server 50 via the management output part 42 b and the fourth acquisition part 51 a. And the fourth acquisition part 51 a acquires the information.

The registration part 53 associates the information acquired by the fourth acquisition part 51 a with the field information and registers the information in the storage part 52. Incidentally, the information may be transmitted to the server 50 simultaneously with the moving image shooting, or may be transmitted to the server 50 after the moving image shooting is ended.

On the other hand, if the management machine 30 determines that the first call information, the second call information, and the third call information are not output, it confirms whether or not the fourth notification information is output. When receiving the fourth notification information, the management machine 30 transmits the fourth notification information to the server 50.

If there is no field registration instruction and neither the first call information, the second call information, or the third call information is received, the server 50 checks whether the fourth notification information is output from the management machine 30. When the server 50 acquires the fourth notification information, the registration part 53 associates the fourth notification information with the field information and stores it in the storage part 52.

If there is no field registration instruction and neither the first call information, the second call information, or the third call information is received, the server 50 checks whether the fourth notification information is output from the management machine 30. When the server 50 acquires the fourth notification information, the registration part 53 associates the fourth notification information with the field information and stores it in the storage part 52.

Specifically, the portable terminal 60 is operated to transmit an update instruction (update information) of the notification determination condition from the update instruction part 51 b 1 of the server 50 to the dispatching part 20 or the management machine 30. Upon receiving the update information from the server 50, the dispatching part 20 or the management machine 30 transmits the update information to the communication device 10.

The communication apparatus 10 updates the notification determination condition based on the received update information. In the present embodiment, the values of the predetermined thresholds F1, F2, and F3 of the notification determination condition are changed.

When the setting button 106 of the home screen Q1 is selected, as shown in FIG. 20, the screen display of the display part 62 transitions to display a setting screen Q 4 as shown in FIG. 15. When the condition change button 409 on the setting screen Q 4 is selected, the monitor change screen Q 5 is displayed.

In the present embodiment, “high” 501, “medium” 502, and “low” 503 on the monitor change screen Q 5 indicate the accuracy of the notification determination condition. If “high” 501 of the monitoring change screen Q 5 is selected, the values of the predetermined thresholds F1, F2, F3 are set smaller than the predetermined thresholds F1, F2, F3 of “medium” 502.

Further, when “low” 503 of the monitor change screen Q 5 is selected, the values of the predetermined thresholds F1, F2, F3 are set to be larger than the predetermined thresholds F1, F2, F3 of “medium” 502. That is, when “high” 501 is selected, the monitoring accuracy is set high, and if “low” 503 is selected, the monitoring precision is set low.

If “medium” 502 is selected, the monitoring accuracy is set between “high” 501 and “low” 503.

When one of “high” 501, “medium” 502, and “low” 503 on the monitoring change screen Q 5 is selected, the selected update information is transmitted from the portable terminal 60 to the server 50.

In the present embodiment, the update of the notification determination condition is to be changed to a preset predetermined threshold value, but even if the threshold value can be freely changed, such as by directly inputting the threshold value Good.

When the transmission of the update information is completed, on the display part 62 of the mobile terminal 60, the screen display of the display part 62 transitions to the home screen Q1 as shown in FIG. 20.

When the server 50 receives the update information from the portable terminal 60, the update information is transmitted from the update instruction part 51 b 1 of the server 50 to the management machine 30 and/or the dispatching part 20. That is, the notification determination condition of the communication device 10 can be updated via either the management machine 30 or the dispatching part 20.

Hereinafter, a case of updating the notification determination condition via the management machine 30 will be described.

The management device 30 updates the notification determination condition of the communication device 10 in the same procedure as the mapping mode. For example, the management machine 30 that has received the update information from the update instruction part of the server 50 moves to the field 3 where the communication device 10 is installed.

The management machine 30 that has moved to the field 3 detects the identification information output from the communication device 10. The management machine 30 requests connection to the communication device 10 matching with the identification information recorded in the management storage part 46 or the storage part 52. The communication device 10 which is requested to connect makes a connection with the management device 30.

The management device 30 designates the determination condition update mode to the communication device 10. The management device 30 and the communication device 10 disconnect communication. Based on the threshold value stored in advance in the management storage part 46, the position detection part 41 acquires positioning information at a point where the strength of the identification information (radio wave) acquired by the first acquisition part 43 is equal to or greater than the threshold value.

The management machine 30 checks whether it is in the mapping mode. When it is not the mapping mode, that is, in the case of the judgment condition update mode, the management machine 30 outputs update information.

The communication device 10 checks whether it is in the determination condition update mode. In the case of the determination condition update mode, the communication device 10 receives the update information from the management machine 30, and the determination updating part 13 updates the notification determination condition.

The management device 30 requests the communication device 10, which has completed updating of the notification determination condition, to update the identification information via the management output part 42 b and the reception part 12 a. The communication apparatus 10 updates the identification information in response to a request from the management machine 30. The management device 30 and the communication device 10 disconnect communication.

The associating part 45 associates the positioning information of the communication device 10 whose update of the notification determination condition is completed with the updated identification information. The associated information is stored in the management storage part 46. Or is temporarily stored in the management storage part 46 and transmitted to the server 50 via the management output part 42 b and the third acquisition part 21 a.

The registration part associates the information with the field information and registers it in the storage part 52. The management machine 30 may be configured to transmit the update information to the dispatching part 20 to update the notification determination condition via the dispatch part 20.

Hereinafter, a case of updating the notification determination condition via the dispatch part 20 will be described.

When the dispatching part 20 has not received the notification information and the activation information of the communication device 10, the dispatching part 20 confirms whether update information has been received from the server 50 or the management device 30. When the update information is received, the third acquisition part 21 a acquires the update information.

The dispatching part 20 requests connection to the communication device 10. The communication device 10 that has made a connection request connects to the dispatching part 20. The communication device 10 checks whether it is in the determination condition update mode. The communication device 10 receives the updated notification determination condition from the dispatching part 20, and the determination updating part 13 updates the notification determination condition. After updating the notification determination condition, the communication with the dispatching part 20 is disconnected.

Hereinafter, with reference to FIG. 4a series of operations of the communication device 10 will be described.

After the activation, the communication device 10 initializes the transmission power of the outputting part 12 b and outputs identification information (S 11).

After the activation of the communication device 10, the judgment updating part 13 initializes the notification judgment condition, and after the updating of the notification judgment condition, the judgment updating part 13 sets the updated notification judgment condition (S 12).

After the setting of the notification judgment condition by the judgment updating part 13, the physical quantity detecting part 11 starts to detect the physical quantity (S 13).

After the physical quantity detecting part 11 starts the detection, the process shifts to the process in the monitoring mode (the monitoring mode process) shown in FIG. 5A. It is judged whether a connection request is requested by the management machine 30 (S14), and repeats the monitoring mode process until the connection request is made.

If the connection request is issued, the process shifts to the connection process shown in FIG. 5C. After the connection process finishes, the communication device 10 is reactivated.

Next, with reference to FIG. 5A, the monitoring mode process of the communication device 10 will be described.

After the transition to the monitoring mode process, the notification creating part 12 c of the communication device 10 judges whether the physical quantity detected by the physical quantity detecting part 11 is matched with any one of the notification judgment conditions (S 21).

In the case where the physical quantity is not matched with any of the notification judgment conditions (S21, No), the outputting part 12 b of the communication device 10 sets the identification information (S22).

The outputting part 12 b of the communication device 10 outputs the identification information (S 23).

In the case where the first condition of the notification judgment conditions is satisfied (S24, Yes), the notification creating part 12 c sets (creates) the first notification information (S25).

The outputting part 12 b of the communication device 10 outputs the first notification information created by the notification creating part 12 c (S 23).

In the case where the second condition of the notification judgment conditions is satisfied (S26, Yes), the notification creating part 12 c sets (creates) the second notification information (S27).

After the notification creating part 12 c creates the second notification information, the communication device 10 shifts to the stealth mode setting process shown in FIG. 5B.

In the case where the fourth condition of the notification judgment conditions is satisfied (S28, Yes), the notification creating part 12 c sets (creates) the fourth notification information (S29).

The outputting part 12 b of the communication device 10 outputs the fourth notification information created by the notification creating part 12 c (S 23).

Next, a process of setting the stealth mode by the communication device 10 will be described with reference to FIG. 5B.

The notification creating part 12 c creates the second notification information (S 27), and after the process is shifted to the stealth mode setting, the notification creating part 12 c judges whether or not the third condition of the notification judgment conditions is satisfied (S 31).

In the case where the second condition is satisfied and the third condition is not satisfied (S 31, No), the output of the outputting part 12 b is initialized, and the output of communication is increased (S 32).

In the case where the third condition is satisfied (S 31, Yes), the notification creating part 12 c sets (creates) the third notification information (S 33).

The communication device 10 checks whether a connection is requested by the dispatching part 20 (S 34).

In the case where no connection is requested by the dispatching part 20, the outputting part 12 b of the communication device 10 lowers the output of the communication of the third notification information created by the notification creating part 12 c (S 35).

When the connection is requested by the dispatching part 20, the connection is established in accordance with the connection request (S 36).

When the dispatching part 20 issues, to the receiving part 12 a, a request for increasing the output of the outputting part 12 b (S 37, Yes), the communication device 10 increases the output of the outputting part 12 b and outputs the third notification information from the outputting part 12 b (S 38).

After confirming the request for increasing the output of the outputting part 12 b, the communication device disconnects the communication (S 39).

When the communication device 10 determines that there is no request for increasing the output from the dispatching part 20 (S37, No) (S37), the communication device 10 disconnects the communication (S40).

The management machine 30 requests the communication device 10 for which registration of the agricultural field information has been completed to update the identification information, through the management outputting part 42 b and the receiving part 12 a (S118).

After disconnection of communication with the communication device 10 (S 119), the management device 30 starts to detect the output of the other communication device 10 (S 102).

In the case where the management machine 30 determines that it is not in the mapping mode (S 111, No), that is, in the case of the judgment condition update mode, the management machine 30 outputs the update information to the communication device 10 (S 114).

The management machine 30 requests the communication device 10, whose update of the notification judgment condition has been completed, to update the identification information (S 118).

After disconnection of the communication with the communication device 10 (S 119), the management device 30 starts to detect the outputting of the other communication device 10 (S 102).

Next, with reference to FIG. 10, a series of operations of the server 50 will be described.

After the activation, the server 50 confirms whether an instruction for switching to the mapping mode is issued from the mobile terminal 60.

When the server 50 determines that an instruction for switching to the mapping mode (an agricultural field registration instruction) has been received (S 121, Yes), the registration instructing part 51 b 2 issues, to the management machine 30, an instruction for switching to the mapping mode (S 122).

The registration part 53 of the server 50 associates the agricultural field information with the association information and registers them to the storage part, the association information associating the positioning information transmitted from the management machine 30 with the updated identification information and in the storage part 52 (S 123).

When the server 50 determines that an instruction for switching to the mapping mode (an agricultural field registration instruction) has not been received from the mobile terminal 60 (S 121, No), the server 50 checks whether the fourth obtaining part 51 a has obtained the calling information (S 124).

In the case where the server 50 determines that the calling information has been obtained (S 124, Yes), the server 50 specifies the positioning information of the communication device 10 that outputted the notification information, based on the calling information, the association information, and the agricultural field information, and transmits the positioning information of the communication device 10 that has outputted the calling information to the management machine (S125).

The server 50 obtains information associating the moving image data transmitted from the management machine 30 with the identification information (S 126).

When the server 50 determines that the calling information has not been received (S 124, No), the server 50 judges whether or not the fourth notification information has been obtained (S 127).

When the server 50 determines that the fourth notification information has been obtained (S 127, Yes), the registration part 53 associates the fourth notification information with the agricultural field information, and stores them to the storage part 52 (S 128).

The server 50 confirms whether the update information has been received from the mobile terminal 60 (S 129).

When the server 50 determines that the update information is received from the mobile terminal 60 (S 129, Yes), the update instruction part 51 b 1 transmits the update information to the management machine 30 and/or the dispatching part 20 (S 130).

As described above, the field management system 1 includes a plurality of communication devices 10, a signal reception part 42 a, a position detection part 41, a first acquisition part 43, a second acquisition part 44 and an association part 45. According to this, only by setting a plurality of communication devices 10 in the field 3 and outputting the identification information to the management device 30, the identification information of the plurality of communication devices 10 and the identification information can be transmitted to the management device 30 Can be easily associated with each other.

In other words, by setting the plurality of communication apparatuses 10 in the field and moving the management apparatus 30 having the position detecting part 41, it is possible to acquire the field information in which the identification information of the communication apparatus 10 and the positioning information detected by the position detecting part 41 are associated You can create a map.

Further, the output part 12 b outputs the identification information as a radio wave.

As a result, the identification information can be transmitted to the management machine 30 or the like with power saving. In addition, the communication device 10 can be easily managed after installation and installation.

Further, the output part 12 b outputs the identification information as an optical signal. The communication device 10 such as an optical signal, for example, the infrared communication device 10 and the like has a feature that the secrecy of information to be output is low compared with the electric wireless communication device 10 and the like at low cost.

Thereby, it is easy to realize the installation of a large number of communication devices 10 in the field 3, and it is possible to prevent cracking or the like intervening in the field management system 1 from the outside illegally.

In addition, the associating part 45 associates the positioning information at the point where the intensity of the radio wave received by the first acquiring part 43 is equal to or more than the threshold and the identification information of the output part 12 b. Thereby, based on the association information associated by the associating part, it is possible to accurately specify the position of the point where the individual communication device 10 is installed.

The associating part 45 associates the positioning information at the point where the intensity of the optical signal received by the first acquiring part 43 is equal to or larger than the threshold with the identification information of the output part 12 b. Thereby, based on the association information associated by the associating part, it is possible to accurately specify the position of the point where the individual communication device 10 is installed.

Further, the output part 12 b outputs the light emission pattern indicating the identification information of the plurality of communication devices 10. Thereby, it is possible to allocate optical signals to individual communication devices 10 without the identification information of the communication device 10 overlapping each other.

The field management system 1 includes a registration part 53 that associates the identification information and the positioning information of the communication device 10 correlated by the associating part 45 with the information of the field. Thus, it is possible to easily create a field map in which the identification information of the communication device 10 and the positioning information are associated with each field.

Further, the field management method includes a step of outputting identification information of the communication device 10 installed in the field 3, a step of the management machine 30 receiving the identification information, a step of positioning the management device 30 based on the signal from the positioning satellite A step of acquiring identification information of the communication device 10 received by the management device 30; a step of acquiring positioning information of the management device 30 detected by the management device 30; a step of acquiring positioning information of the management device 30 and associating the identification information of the communication device 10 acquired in the acquiring step with the positioning information of the management device 30 acquired in the step of acquiring the identification information of the communication device 30.

The notification determination condition is that when the reception part 12 a receives the activation information, the notification information to be output from the output part 12 b or the output of the output part 12 b Includes conditions to change.

Thus, the output of the output part 12 b in the communication device 10 can be changed. The communication device 10 can change the output of the output part 12 b, that is, the output of the identification information and the notification information, depending on the situation. For example, when it is detected that the communication device 10 is carried away, by lowering the output of the output part 12 b, communication from the communication device 10 to the outside can be temporarily stopped.

On the other hand, by raising the output of the output part 12 b after the communication device 10 is taken away, the position of the carried-out communication device 10 can be conveyed.

The call determination part 21 c creates call information having different contents from the call condition based on the plurality of notification information acquired by the third acquisition part 21 a. According to this, according to a plurality of pieces of notification information, it is possible to stepwise decide whether or not to call the management machine 30 and notify the management machine 30 thereof.

The calling condition is a condition based on the combination of the content of the notification information and the notification information output from the plurality of communication devices 10. Thereby, it is possible to determine the communication device 10 with a high urgency of calling.

Also, in addition to being able to make a majority decision on the notification information outputted from each communication device 10, the management device 30 can be dispatched preferentially from the communication device 10 with a high urgency of calling.

The management machine 30 has a first obtaining part 43 that obtains the call information output by the calling part 21 b, and moves to the field according to the call information. The call determination part 21 c and the calling part 21 b are provided in the server 50. The call determination part 21 c creates call information based on the notification information output by the output part 12 b, and the call part 21 b transmits the call information to the server 50. As a result, the field 3 can be monitored with a configuration including at least the communication device 10, the dispatching part 20, and the management machine 30 without involving the server 50 or the like.
